"Is this the space gate that left this world?" Hida exclaimed, and by this time everyone had all stood in the garden on the top floor, watching the spectacular scene of Laputa crossing the barriers between the worlds.

"Yes, but rest assured, our trip was completely safe. Ryan comforted everyone that when Hilda asked Ryan to take Laputa to other worlds, this Sky City already belonged to Ryan, which meant that Ryan could take Sky City with him.

Concerned about the safety of the two children, Ryan suggested that they could leave with Sky Castle. After a short period of consideration, Balu and Hilda agreed, after all, they were both orphans and had no relatives to care about in this world. As for their friends, as the main target of the enemy, if they can disappear in this world, it will make their friends safer and will not get involved in dangerous right and wrong.

Although they are the protagonists of the cartoon, Balu and Sida, who are ordinary people, don't need many offset points. For just 20 offset points, Plants vs. Zombies opened the door for them.

Yes, Hida they chose the world of Plants vs. Zombies. They left a lot of psychological shadows in the process of being hunted down by careerists and careerists before, so when they knew that they could choose the world, they just chose Plants vs. Zombies, the world with the least number of humans, without hesitation after a brief discussion.

Although Ryan provided a lot of technology and traveled to the world of Plants vs. Zombies many times to strangle and kill a steady stream of zombies, and even after becoming a legend, Ryan cleaned up all the zombies within ten kilometers of their previous occupation area in one go, which greatly reduced the power of zombies. But in that world, humanity is still a weak part.

The main core problem here is that after a long zombie apocalypse, there aren't many humans left alive. Even after so many years of collecting, Ryan and his team have only managed to recruit a population of more than 100,000, which is already more than half of the planet's concentrated population.

Fortunately, now with the combined help of plants, robots, various high-tech weapons and alchemy props, human beings have finally blocked the attack of zombies and escaped the fate of possible extinction at any time. One day, humanity in this world will finally regain control of this planet.

The scene of crossing the barrier of the world is indeed spectacular, after a huge blue space door opens, Laputa uses the little power left to submerge into the space door and step into another world. It's just that what they don't know is that the magnificent scene of the city in the sky crossing the world was photographed by people on a passenger ship on the sea, and it became the last trace of this legendary city left in the world.

"It doesn't look like we're in the same world. Balu said, passing through the space gate, the entire sky city appeared above the sea on the edge of the green leaf plain. After seeing the blue sky and snow-white clouds, Balu and Hilda immediately looked around.

Green Leaf City spotted them as soon as Sky Castle appeared above the sea, and soon Dave appeared on the top platform of Sky Castle in a helicopter.

"Ha, my friends, Dave is glad to meet you. As soon as he saw Ryan, Dave gave him a warm hug. Then he took a step back and asked, "By the way, why did you take a city floating in the sky with you this time?"

"That's a long story—" For the rest of the day, Ryan spent seven or eight minutes briefly explaining what they had encountered in the world of Sky City, and then introduced Baloo and Hilda to Dr. Dave.

"Rest assured, no one here is going to fight for those frivolous ambitions. Dave assured the two children with the thumping of his chest, "Because there are only a few of us together, and we're all busy trying to survive." ”

"Do you need a mechanic here?" asked Baloo. "I grew up in the mine since I was a child, and I learned a lot of maintenance principles and operation methods of machines from my master. ”

"Mechanics, of course. Dave said. "But you should go to school at your age and learn how those machines work. We need mechanical engineers more than mechanics. After all, we now have enough robots to do the kind of simple and repetitive work that requires a lot of manpower, but how to improve robots and boilers is a university question. ”

"So I'll only herd cattle, what should I do in the future?" Hilda looked like she was about to cry after hearing Dave say that the robots could do simple jobs here, and she was worried that she would become a burden to everyone and be left behind.

"Don't be discouraged, little girl. Dave struggled to squeeze out a gentle smile. "You can go to school with your friends and choose a future career when you come out of school. In addition, raising animals here is also an important job. The meat that grows from the trees is only suitable for luncheon meat or ham sausage, and people always want to eat real meat as their living standards improve. ”

That's why Ryan had to develop farming in the world of A Song of Ice and Fire before, for those newly emancipated slaves, meat was enough at first, but as the world progressed, their demand would increase one day. Fortunately, the five dragons grew up, and they only paid attention to nutrition and not taste. These plant-based meats are just right to feed dragons.

After pacifying the two children who had left their hometown and had come to a strange new world, and preparing a place and school for them, a group of professionals arrived at the Sky City with robots and began to conduct a comprehensive inspection of the ancient city.

The results were not promising, and although the shell of the core area was extremely hard, the mana flow circuit inside had become somewhat incomplete due to the invasion of tree roots. In addition, the buildings outside the core area are heavily weathered, and most of them are held in place purely by huge tree roots, which may collapse and fall at any time.

"It seems that it can only be strengthened by means of alchemy. After reading the list sent over after the inspection, Ryan sighed, the overall aging of building materials is difficult to repair through ordinary reinforcement. Especially now that you don't want to destroy the ecosystem at the top of Sky City, the common means of demolition and reconstruction are no longer available.

Fortunately, it didn't take much energy or materials to just reinforce the building debris on Sky City, especially after Ryan used natural magic to awaken the tree above, and the Psychic Tree helped a lot in the reinforcement work.

Therefore, in addition to strengthening the sky city of Laputa during this time, Ryan's remaining energy was used to make and research on the production and research of flying stone crystals. Because the crystallization was most likely made by accident, the Laputas did not use the usual alchemical encryption technique on the crystallization. In just three days, Ryan had mastered how to make flying stone crystals.

After successfully analyzing the use of the Flying Stone Crystal, Ryan began to build his own castle in the sky. Based on what he had learned from Silvermoon City last time, he planned to build a floating magic tower that would combine the strengths of each world, just like the one that Lady Erastro had in Silvermoon City.

"Can our floating city become a magical building as powerful as Hogwarts Castle?" Hermione asked in a whisper after watching Ryan seal the flying stone that took a week to make into a hollow golden ball with a diameter of two meters, a magic circle filled with Mithril and inlaid with magic gems on the magic nodes, Hermione asked in a low voice, as if asking Ryan, as if asking herself.

"No problem, I'm convinced that this castle will one day become even greater than Hogwarts Castle. Looking at the golden ball that slowly floated at a height of about a meter above the ground after it was made, Ryan took Hermione's hand and whispered. "This is true both for the owner of the castle and for the castle itself. ”
